Editing the audio for a music video

My friend and I are making a music video of the Chainsmokers - All I know feat. Phoebe Ryan that came out last week. We have recorded the audio, but we aren't satisfied with how it sounds yet. She is a very good singer, but we feel some audio manipulation is needed in order to make it sound professional.

We need this to be done by Sunday (Approximately 10GMT) the 9th of October, 2016. This project will not take more than a few hours I hope, so I hope the time limit is not too short. If you desperately need more time, we can discuss it.

I will post links to the audio files, once we can talk with one another.
